While it was formerly believed that the population of the world was increasing at an alarming rate, recent opinion has been greatly influenced by the phenomenon of declining populations, not only of native races but also of some sections of the white race. Human races and nations probably perform a cycle in their evolutions: birth, maturity, and gradual decline. The dominant stocks rise at the boundary line of the old declining populations, probably on account of crossbreeding with other races. The new historical races form a very small portion of the new types produced by racial crossings since a vastly greater number have failed. Development stops when the power of reproduction declines. The old stock is sometimes pushed aside and confined in inhospitable areas where the aims of the conqueros do not reach. Geneticists have established the origin of new races by crossbreeding, and these facts confirm the cyclical theory of the evolution of population. Decadence sets in when isolation continues for a long period. The Teutonic race which is "passing" has made notable contributions to civilization, but the feeling of superiority will prevent their descendants from being the forefathers of the rulers of tomorrow. Among the expanding races are the Slavs, Japanese, Chinese, Malayans, and certain mixed races in Africa and South America. There is no race on earth which cannot, when its turn has come, boast of good claims to hold the helm of mankind.
